The overarching motivation for this work is the need to predict the geoeffectiveness of interplanetary coronal mass ejections CMEs. This is a complex problem, requiring an understanding of the magnetic structure that leaves the Sun in a CME, of how it propagates through and interacts with the solar wind, and of how it impacts the Earths magnetosphere and couples with the upper atmosphere. We focused on the weak link in the very beginning of this chain what is the internal magnetic structure of the CME The goal of our project was to develop a new methodology for assimilating coronal magnetic diagnostic data into magnetohydrodynamic MHD models in order to establish not only the magnetic structure of the source region of coronal mass ejections CMEs, but also the global field into which it erupts. Our project name is Data-Optimized Coronal Field Model, or DOCFM.
